High-ductility geopolymer and preparation method thereof
The invention discloses a high-ductility geopolymer which is prepared from the following raw materials in parts by weight: 32-38 parts of fly ash, 7-9 parts of Portland cement, 4-5 parts of calcined metakaolin, 13 parts of silicon powder, 28-32 parts of quartz sand, 2-3 parts of sodium hydroxide, 4-8 parts of sodium silicate, 4-5 parts of water and 0.5-0.7 part of polypropylene fiber. The ductility of the high-ductility geopolymer disclosed by the invention is relatively high and is 300% of that of a common ductility geopolymer; the early strength is high, the later strength can be kept unchanged or slightly increased, and the compressive strength of the prepared high-ductility geopolymer is improved by 200% compared with that of a common geopolymer; in addition, the preparation process ofa composite alkali activator solution is omitted, the production process is simplified, and the method is easy to popularize and use.
本发明公开了一种高延性地聚合物，原料组成按重量份数计如下：粉煤灰32‑38份，硅酸盐水泥7‑9份，煅烧的偏高岭土4‑5份，硅粉1‑3份，石英砂28‑32份，氢氧化钠2‑3份，硅酸钠4‑8，水4‑5份，聚丙烯纤维0.5‑0.7份。本发明的高延性地聚合物的延性较高，是普通延性地聚合物延性的300％；早期强度高，且后期强度能保持不变或略成上升的趋势，制备的高延性地聚合物抗压强度较普通地聚合物强度提高200％；另外本发明省略了复合碱激发剂溶液的配置过程，简化了生产工艺，易于推广使用。
